Amy Winehouse AWINEHOUSE103107_04.jpg

Sky News is reporting that Amy Winehouse has been arrested "by appointment" today in London.

According to Sky, it's been expected that Amy would have been hauled in for questioning about any "potential involvement" in her husband, Blake Fielder-Civil's current case.

Amy's been on quite a downward spiral ever since Blake's incarceration due to allegations of grievous bodily harm and perversion of justice. Let's hope the Grammy nominee sees much better things to come in 2008!
